Я пытаюсь подключиться к хосту с использованием случайного снятия отпечатков TLS. Я использую https://github.com/refraction-networking/utls (см. Мою проблему, которую я создал на https://github.com/refraction-networking/utls/issues/42)
Моя проблема сейчас, как я могу использовать прокси HTTP или SOCKS5 в то время как открывая это соединение?
Код, который я сейчас использую:
package main
import (
"bufio"
"fmt"
"log"
"net"
"net/http"
"net/http/httputil"
"net/url"
"time"
"github.com/refraction-networking/utls"
)
var (
dialTimeout = time.Duration(15) * time.Second
)
var requestHostname = "google.com"
var requestAddr = "172.217.22.110:443"
// this example generates a randomized fingeprint, then re-uses it in a follow-up connection
func HttpGetConsistentRandomized(hostname string, addr , uri string) (*http.Response, error) {
config := tls.Config{ServerName: hostname}
tcpConn, err := net.DialTimeout("tcp", addr, dialTimeout)
if err != nil {
return nil, fmt.Errorf("net.DialTimeout error: %+v", err)
}
uTlsConn := tls.UClient(tcpConn, &config, tls.HelloRandomized)
defer uTlsConn.Close()
err = uTlsConn.Handshake()
if err != nil {
return nil, fmt.Errorf("uTlsConn.Handshake() error: %+v", err)
}
uTlsConn.Close()
// At this point uTlsConn.ClientHelloID holds a seed that was used to generate
// randomized fingerprint. Now we can establish second connection with same fp
tcpConn2, err := net.DialTimeout("tcp", addr, dialTimeout)
if err != nil {
return nil, fmt.Errorf("net.DialTimeout error: %+v", err)
}
uTlsConn2 := tls.UClient(tcpConn2, &config, uTlsConn.ClientHelloID)
defer uTlsConn2.Close()
err = uTlsConn2.Handshake()
if err != nil {
return nil, fmt.Errorf("uTlsConn.Handshake() error: %+v", err)
}
return httpGetOverConn(uTlsConn2, uTlsConn2.HandshakeState.ServerHello.AlpnProtocol, uri)
}
func main() {
var response *http.Response
var err error
response, err = HttpGetConsistentRandomized(requestHostname, requestAddr, "/2.0/ssocookie")
if err != nil {
fmt.Printf("#> HttpGetConsistentRandomized() failed: %+v\n", err)
} else {
//fmt.Printf("#> HttpGetConsistentRandomized() response: %+s\n", httputil.DumpResponse(response,true))
dump, err := httputil.DumpResponse(response, true)
if err != nil {
log.Fatal(err)
}
fmt.Printf("%+s\n", dump)
}
return
}
func httpGetOverConn(conn net.Conn, alpn string, uri string) (*http.Response, error) {
req := &http.Request{
Method: "GET",
URL: &url.URL{Host: "www." + requestHostname + uri},
Header: make(http.Header),
Host: "www." + requestHostname,
}
req.Proto = "HTTP/1.1"
req.ProtoMajor = 1
req.ProtoMinor = 1
err := req.Write(conn)
if err != nil {
return nil, err
}
return http.ReadResponse(bufio.NewReader(conn), req)
}
